Celtic almost clinched an amazing shock result against Barça in the Camp Nou. Just when the Scottish side thought they were going to clinch a valuable and much needed point following Celtic’s victory in Russia, Jordi Alba showed up at the far past and got on the end of an Adriano cross to score an amazing winning goal for Barça (2-1) in the 94th minute.

Neil Lennon’s men had taken the lead in the 18th minute with a Samaras header that Mascherano deflected into the goal occupied by Víctor Valdés.

Celtic face their most difficult test of the season so far when they step out at Camp Nou in the Champions League tonight to face the almost impossible task of trying to pick up points away to Barcelona.

Tito Vilanova will be required to change his plans in order to middle together a strong side against Celtic. Neither Piqué, Puyol and Alves will be available in time, which means all three will miss the vital Champions League match. This trio of absentees and also Busquets, who is currently suspended.

Both Puyol and Alves were training on their own throughout Monday’s session and neither is yet ready to make an apperance. Piqué has also been ruled out, so Vilanova is yet again going to find it hard at the back.

Mascherano and Song are the only first team options readily available at the centre of defence, as Busquets is starting the first game of his two-match ban after his sending-off against Benfica. Yet again it could be a issue of all hands on deck for Barcelona at the back. Meanwhile, the way the Barça ship carries on leaking goals is a huge cause for worry.

Defensive woes aside, the primary talking point in Tito Vilanova’s squad for the Celtic game is the addition of academy player Sergi Roberto, who will take the position of the suspended Sergio Busquets. Indeed, this is the only switch to the squad named by the coach over the last meet.

Barcelona is sitting on the top of La Liga after a gritty win over a Valencia side that were unlucky to go home without a point.

The Catalans can thank Brazilian defender Adriano for his brilliant strike from over 20-yards-out which proved to be enough for the win while also providing the 27-year-old with his first goal at the Nou Camp.
